To'allwhom'itmay coace mff Be it known. that I,'AUST1N IERRYBERRY,

acitizen' of the United f t'ates', residing at Dulutlnfin thecountyof'btyLouis and State of Minnesota, have invented certain new and usefulImprovements -1n- Sectmnal Fire Grates; and I do hereby declaretl1e:followthereon.

ing to be a full, cleaiyand exact description of the invention, such aswill enable others skilled in" the 'art to which it appertains to makeand use the same.

This invention relates to grates and al-.

though more particularly applicable to grates around a water conduit, isnot lim-' ited thereto.

An object of this invention is to provide a grate of an improved andsimplified structure that will be fireproof and'durable and susceptibleof easy and economical assembly and repair.

A further object of this invention is to provide a sectional grate withsections of an improved and simplified structure.

The invention consists in theno-vel structure and arrangement andcombination of parts as hereinafter more particularly described andclaimed.

Figure l is a side elevation of the right hand grate section; i

Fig; 2 is a side elevation of the left hand grate section;

Fig. 3 is a cross section through assembled sections without thesupporting pipe and shows the tenons of each section;

Fig. at is aside elevation of two sections assembled on a pipe, thelatter in cross section; s

Fig. 5 is a side elevation of a water pipe with grate sections mountedthereon, and Fig. 6 is a plan view of the boiler showing a series ofpipes with my grates mounted In the accompanying drawings it will benoted that each section comprises in detail abody member having a pairof wings 2 projecting in opposite direct-ions from the body, eachsection being provided on one face with tenons 3 and 4t and a slot 5communicating with a semicircular opening in the body of each section,the opposite faces of the body being provided with mortises 3 and 4;arranged in transverse alignment with the tenons 3 and 4:, so that whenthe sections are fitted together as illustrated in Figs. 0 and 4:, thetenons 3 and 4 of one section will fit into the mortises 3 and 4 of thenext adjacent section, On one side of each section portions of the bodyare cutaway as shown-aha and b, so'that when "the sections are fittedtogether, the tenons fitting into theniortises, a space is leftbet'ween'the wing portions 2 of adjacent sections,.,this space being provided toallow the ashes to drop throughthe grate.

Eachsection is mounted over the pipe until the pipe is seated within thearcuate openings within the body of the sections, the sections beingalternately faced in opposite directionsto bring the slots 5STHICCBSSlVQlY on opposite sides of the pipe.

mate with the mortises 3 and-4, as is cl arly illustrated in Fig.

' means for shaking the grateunit.

A spacing bar 7 may bearranged at each end of the series of sections toretain. them in position upon the pipe.

Modifications in the precise form and construction will readily suggestthemselves to those skilled in the art but within the scope of thepresent invention as claimed.

Having thus fully described my invention, I claim: I

1. The combination of a supporting member and a plurality of gratesections, each of said grate sections comprising a body, wings extendingfrom opposite edges of the body, said wings being thinner than the body,each body having a central opening communicating by a slot with one edgeadjacent a wing, and said bodies being further pr0-,

on the pipe P by hav ng the side portions of the slot 5passed' sectionsare then closed together so that the tenons 8 and 4 are engaged and no rvided with mortises on one face and tenons on the other face, saidmortises and tenons being arranged on the respective faces ofthesections which are to be mounted ad acent each other so that thetenons of one I section will mate with the mortises of the next adjacentsection when said sections are arranged with their slotted edges facingin opposite directions.

2. The combination of a fixed supporting member and a plurality ofsubstantially U shaped grate sections, said U-shaped sections beingadapted to be slipped over the supporting member. from opposite sides,and mortise and tenon means carried by each of said sections tointerlock the same to prevent independent rotary or radial movement ofany section, the assembled sections being rotatable upon said supportingmember.

3. The combination of a supporting member and a plurality ofsubstantially U-shaped grate sections, each sectionhaving laterallyextending wings, said Wings being thinner than the body of the U-shapedmember, said U-shaped members being adapted to be slipped over thesupportingmember from opposite sides with said wings in alignment andinterlocking means to prevent independent rotary or radial movement ofanysection...

c' 4:. The combination of a tubular supporting member and a plurality.of interlocking grirtesections, each grate section comprising a U-shapedbody the opening of which is downwardly inclined, laterally extendingwings, and mortise and 'tenon means on its opposite faces respectively,whereby radial and rotary movement between the sections is prevented. T

5. In a device of the character described, an interlocking grate sectioncomp-rising a substantially U-shaped' body having the opening inclineddownwardly, relatively thin wings extending substantially horizontally,and mortises and tenons on. its opposite faces respectively as and forthe pur poses specified. 1 I

In testimony WhereofI affix my signature.
